`cv2.error: OpenCV(4.7.0) :-1: error: (-5:Bad argument) in function 'imshow'

Overload resolution failed:

• mat data type = 17 is not supported
• Expected Ptr for argument 'mat'

code

frame = camera.grab(region=region)  # numpy.ndarray of size (640x640x3) -> (HXWXC)
npImg = np.array(frame)
cv2.imshow('DXCAM EXAMPLE', npImg)
cv2.waitKey(1)

What is the region? Python version? Also you might not need npImg = np.array(frame)
